Abstract

A modified boundary layer modeling approach is used to predict the fracture toughness and crack resistance behaviors of solid oxide fuel cell (SOFC) materials. In this approach, a preexisting sharp crack inside a layer or a t an interface between two different layers is assumed under plane strain conditions. Fracture is allowed to occur in a small process window situated at the crack tip. The process window is contained in a circular region, which can involve one or two different materials and their interfaces. Elastic asymptotic crack-tip fields are prescribed as remote boundary conditions. Special attention is focused on the cracking of the interface between the glass seal and the electrolyte material.
